The connection nodes of modular buildings are mainly divided into three types: inter module connections, internal module connections, and connections between modules and foundations.
Inter module connections include horizontal connections between adjacent modules and vertical connections between stacked modules. The node connection method has a significant impact on the structural performance of modular buildings. Typical inter module connection nodes generally include bolt connections, concrete joint connections, and interlocking connections. Among them, bolt connections are more commonly used in practical applications and require less workspace for installation; Concrete joint connection is suitable for steel-concrete hybrid structures with good overall stability; Interlocking connections can be made after the construction of building components such as partitions is completed.
In December 2025, Guangzhou Second Decoration Co., Ltd., Guangzhou Construction Co., Ltd., and Guangzhou Construction Group Co., Ltd. applied for a patent called "Rapid Connection Pipeline Structure Suitable for Modular Integrated Building Pipeline Through Floor slabs" (Publication No. CN121497895A). This technology achieves a firm positioning of the through floor sleeve in the reserved hole through a clamp seat and a fixing part, limits the displacement of the sleeve, and provides a standard interface for pipeline docking through pipeline connection components, aiming to solve the technical pain points of traditional through floor sleeve fixation and low pipeline docking efficiency.
The issuance date of the national standard plan "Technical Requirements for Steel Structure Box Module Units and Connection Accessories for Buildings" is June 3, 2025. This standard aims to fill the gap in domestic product standards for steel structure box module units, and put forward requirements and inspection methods for the production and integration of steel components, connection nodes, equipment pipelines, decorative components, etc. in box module units, in order to promote the formation of a safe, reliable, and efficient steel structure modular building production and construction mode.
